Title:
WIRELESS ENERGY TRANSMISSION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/237916
Kind Code:
A1
Abstract:
Disclosed is a wireless energy transmission system, comprising a continuous wave signal source, a radio frequency power amplifier, a transmitting impedance matching network, an acoustic-electric channel, a receiving impedance matching network, a radio frequency AC-DC converter and a load circuit electrically connected in sequence, wherein the acoustic-electric channel comprises a transmitting transducer, a receiving transducer and a metal device wall, and the transmitting transducer and receiving transducer are fixed at two sides of the metal device wall. Further disclosed are an impedance matching technology and a radio frequency AC-DC converter based on a resonant rectifier. The system can transmit electrical energy by penetrating a casing of a sealed metal compartment (or container), the need for punching the casings of these metal compartments (or containers) is completely eliminated, and the transmitted electrical energy can be efficiently output to provide a voltage stabilized direct current that can be used by an electronic device, such that many disadvantages of present ultrasonic wireless energy transmission systems are overcome, ultrasonic wireless energy transmission technology is improved, and the practicality of the ultrasonic wireless energy transmission system is improved.
